Cad or 3D scanning expertise needed for blade 18 heat sink

Any updates? I have Razer Blade 18 2024 with rtx 4090.

Hi, so can officially add my blade 18 2023 to the mountain of regretfully bought & broken razer products. In attempt to un-brick my £4K Laptop over a max couple hundred £ part. I was looking at exploring similar options to this and wondered how far you got. Or if you have any info on why you stopped exploring this or what walls in the process you hit. 

My problem is this is my only computer and it still functions enough for me to work on it so I can’t keep it half disassembled while i work on this project. Anyways here’s how im going to try and proceed. 

My process is looking something like this:

step 1 imaging,

Use a basic 2d paper scanner to take a copy of both side of heatsink.

Attempt to take a 3d scan using polycam app on iPhone (although doubt this will assist much)

take depth measurements with caliper

Use these to make a cad model and 3d print prototypes to ensure accurate fit

step 2 manufacturing 

1) Potentially find a manufacturer to make a new heatsink for us. 

2) Modify my cad file to make a block which i could cnc or have made to mount heat pipes to it either by being press fit in or thermal epoxy/solder. Problem with this is attaching cooling fins to it could be difficult.

3) Use this captured info to make a guide to modify the existing vapour chamber to add heat pipes to it. This has the benefit of using pre existing cooling fins however,  is im my eyes the most risky option because with this we only get 1 chance and if it and the other ideas fail that’s truly the end of the laptop and can start stripping it for parts.

Side note on managing expectations. I am not looking to restore my computer to its previous cooling power I know that will be very tricky. My goal is to make my computer usable again without it being strapped to a cooling pad on max 24/7.
